Transform Handle Remote Desktop Crash

[lukeb]

Like many of you, I am working from home for the time being. I have been able to connect to my workstation at work via Remote Desktop and running Vred on that machine. One big annoyance I have come across is the whenever I try to turn on the transform handles in the render window they either are invisible or, most of the time, Vred crashes instantly.

I am using Vred 2020.1 and both machines are running Windows 10.

I'm assuming it is a graphics issue because I am remoting in. Has anyone else had this issue? Any luck fixing it? Anyone have any ideas?

This sounds like VRED is running in no opengl mode. Sadly OpenGL acceleration doesn´t work on remote desktop unless you use a quadro GPU on the remote system (not sure if you need a nvidia gpu on the connecting system as well and sadly I also never tried this with an AMD GPU) . Sadly instead of not just rendering the transform it seems to crash. We probably need to fix that somehow but I think the only way to avoid the crash is to not use manipulators.

Thanks for the reply Michael. I'm a little bummed there isn't a fix for this but hopefully there is in the future. Thanks again!

Hi, have you tried with other remote desktop software?
i didn't tried Vred, but i fond with meny of my customers that with Inventor and Autocad it is better to use something like Anydesk, Google remote desktop or, if your workstation is an HP, the HP Remote Graphic software.
I found that the standard Windows Remote Desktop is not optimized for CAD or software that use heavily your GPU.
Sometimes i use Teamviewer to connect with my office workstation with Vred. Obviously the image quality on your screen depends from the network speed, but it works.

Best

For users running VRED on a system with a Geforce GPU Nvidia has released a patch that enables OpenGL acceleration via windows remote desktop:

NVIDIA provides Windows Remote Desktop support for NVIDIA GeForce GPUs, a feature that has previously only been available on enterprise Quadro boards.

You will first need to log on as an NVIDIA Developer to get access, but after you do this link will enable you to access the software you’ll need:  https://developer.nvidia.com/designworks

It will require you to use GeForce drivers R440 or later.  Once you download, launch the executable as administrator on the machine which runs the OpenGL application to enable OpenGL acceleration. A dialog will be displayed to show whether OpenGL was enabled and if  rebooting is required.

Future GeForce 440 and 445 drivers will have the capability built in, so you won’t need this patch.

Kind regards

Michael

This patch fixed the issue with no problems, so far. Thanks Michael!
